Service & Repair of Burleigh WA-7600 Optical Wavelength Meter

Burleigh WA-7100 & WA-7600 Optical Wavelength Meter – Professional Repair, Alignment & NIST-Traceable Calibration

We offer expert repair, maintenance, and calibration services for the Burleigh WA-7100 and WA-7600 Optical Wavelength Meters—high-precision instruments used for laser characterization, fiber optic testing, and advanced R&D in photonics and telecommunications. These wavelength meters are known for their sub-picometer resolution, internal HeNe laser referencing, and exceptional repeatability. If your unit is drifting, failing to detect signals, or showing hardware or alignment errors, our experienced technicians are ready to restore it to peak performance with precision alignment and certified calibration.

Our Repair & Calibration Process

Thorough Diagnostics & Functional Testing
Each WA-7100 or WA-7600 unit is fully tested upon arrival to evaluate:

• Wavelength measurement accuracy and resolution

• Internal HeNe reference laser output and lock stability

• Signal strength and detector sensitivity

• Motorized scanning interferometer and encoder response

• GPIB/RS232 communication interface functionality

• System boot integrity and front panel operation

Our testing setup uses tunable laser sources, optical references, and loopback configurations to simulate real operating environments.

Common Issues We Repair

• No signal detection or incorrect wavelength display

• Drifting or fluctuating wavelength measurements

• Aging or failed internal HeNe laser source

• Detector degradation or low optical signal-to-noise ratio

• Motor or encoder failure in scanning interferometer

• System errors during startup or warm-up cycle

• Communication failure via GPIB or serial interface

• Internal alignment issues causing wavelength instability

Component-Level Electronics & Power Repair
Our team performs board-level diagnostics and repair, including:

• Replacing failed power components, regulators, and relays

• Repairing analog front-end, digital control boards, and laser drivers

• Restoring detector amplifier chains and signal conditioning circuits

• Repairing or replacing failing display boards and front panel interfaces

Interferometer & Optical Realignment
Precision is critical in the WA-7100 and WA-7600. We:

• Realign the internal Michelson interferometer

• Replace or realign optics, mirrors, and collimators

• Clean fiber ports and optical windows

• Realign the internal HeNe reference laser for lock stability and measurement consistency

Firmware Testing & Communication Validation
We verify that all onboard firmware is functioning and that the unit communicates properly with external systems using GPIB or serial protocols. This includes testing command response, data export, and remote control capabilities.

NIST-Traceable Final Calibration
Every repaired unit undergoes full NIST-traceable calibration, including:

• Wavelength accuracy validation with reference lasers

• Scan repeatability and resolution testing

• Power level sensitivity verification (if supported)

• Data output comparison against certified standards
  A full calibration certificate with before-and-after performance data is provided.
